Researchers have cured mice with a genetic blood disease by correcting mutated genes in blood cell-producing stem cells. The method offers a new therapeutic approach for treating blood disorders, such as sickle cell disease and thalassemia. The gene-editing technique can be administered easily into living animals and notably decreases off-target effects…

A new engineered gene therapy virus, inserted into blood stem cells and then transplanted into mice with sickle cell disease, markedly reduced red blood cell damage according to the study “Lineage-specific BCL11A knockdown circumvents toxicities and reverses sickle phenotype,” published in the Journal of Clinical Investigation. A clinical gene therapy trial…
